The Environmental Protection Agency is requiring the city of Manchester to alert residents when it discharges raw sewage into the Merrimack River. The change is part of a large agreement Manchester is finalizing this year with the EPA to ensure the city's wastewater and stormwater systems comply with the 1994 Clean Water Act.

Manchester's Amoskeag Fishways, the state’s largest urban environmental education center, is scaling down its operations next week.

The center is located at Amoskeag dam along the Merrimack River. For nearly 25 years, New Hampshire Audabon has run it, offering free environmental and marine education to around 25,000 people each year.

Two environmental groups plan to sue the owners of a coal-fired power plant outside Concord – Merrimack Station, the largest of its kind left in New England.

A sewage treatment plant in North Andover, Massachusetts, lost power during the powerful wind storm and spilled 8 million gallons of untreated waste into the Merrimack River.

North Andover Town Manager Andrew Maylor said Tuesday a pump failed to move waste into the treatment plant because of the power outage. That allowed waste to back up and flow in the river.

He says there was backup power for the sewage treatment plant, but not the pump outside the plant.
